Title: Improvements in damping valves for shock-absorbers, resilient devices, dash-pots, and the like
IPC: F16F9/48
Filed: 1942-07-28
Abstract: 566,999. Shock-absorbers &c. DOWTY EQUIPMENT, Ltd., and BINGHAM, A. E. July 28, 1942, No. 10570. [Class 108 (iii)] Relates to a resilient fluid - friction device, shock-absorber or the like comprising a plunger 7 slidable in the end of a chamber 4 and having a damping- head or piston 8 carrying a metering valve 9 which is movable relatively to the piston under fluid pressure to provide a variable damping effect. According to the invention, an enlarged head 15 or 16 on the valve 9 operates as a piston with a fluid flow restrictive clearance effect in a recess 18 or 19 in the piston 8 as the valve reaches a limit position, in order to entrap between the valve head and recess a cushion of fluid with such restricted escape that violent engagement of the valve head with the piston 8 is avoided. When, as shown, the valve has two enlarged heads, one may be formed integral with the valve stem and, to facilitate installation of the valve, the other may be screwed on to a spigot fitting and finally fastened by a rivet or dowel 17. Both heads, however, may be integral with the valve stem and the valve located on the piston 8 by means of a split bush. The valve 9 is formed with an axial bore 10 and spaced lateral ports 11, 12, 13 or a tapering duct or ducts and modifications as described in Specification 566,998 may also be incorporated in the valve. To obtain a prolonged cushioning effect, the piston recesses 18, 19 may be considerably deeper than those shown or either or both recesses may be formed in a part or parts projecting from the piston. A liquid-restricting passage 14 provided in the piston may be dispensed with if the bore 10 extends right through the valve.

Abstract: 970,623. Discharging hoppers. AUTOPACK Ltd. March 15, 1963 [March 20, 1962], No. 10584/62. Heading B8A.  A screw 3 is driven at two speeds to discharge material from hopper 1 down into a container therebeneath. Both speeds are derived from motor 14. The first and fastest speed is transmitted from motor 14 to screw 3 via gear 17, belt 22, pulley 20, sleeve 12 and clutch 8, the drive then passing from spindle 7 through gears 6 and 5 to shaft 4 of screw 3. The second and lowest speed is transmitted to screw 3 from the motor 14 via gear 15, chain 18, gear 19, sleeve 13, clutch 9 and thence (as before) from shaft 7 via gears 6 and 5 to the shaft 4 of screw 3. The screw 3 therefore is driven for a predetermined period at a first higher speed and then at a second lower speed. The change of speed is effected by timer 43 which is driven from shaft 7 via gear 27, gear 29, pin 37, disc 38 and pinion 42. Operation.-When motor 14 is first driven to drive screw 3, clutch 8 is operated to drive the screw at the higher speed. At the same time the shaft 41 of the timer 43 is also driven. The timer then operates a switch to declutch clutch 8 and to clutch in clutch 9 so that the continued rotation of motor 14 drives screw 3 at the lower speed. Finally, the timer operates another switch to declutch clutch 9 and to operate brake 24 to stop the screw 3. Agitator 36.-The agitator in hopper 1 is driven from motor 14 via shaft 7, gears 27 and 29, gearing 31, chain 33 and sleeve 35. Specification 970,664 is referred to.

Title: Improvements in or relating to electron discharge devices
IPC: H01J43/04
Filed: 1938-04-08
Abstract: 493,751. Cathode-ray tubes and circuits therefor. FERNSEH AKT.-GES. April 8, 1938, No. 10799. Convention date, April 8, 1937. [Classes 39 (i) and 40 (v)] In an electron-discharge device the proportion of electron current of a single electron beam passing through an apertured control electrode or falling on a collecting electrode is varied by deflecting fields acting independently in two directions at right-angles. The electron stream from a thermionic cathode 2 is concentrated by a Wehnelt electrode 3 on an aperture in a diaphragm 4; the aperture is preferably rectangular but has at least two mutually rectangular sides. The image of the aperture is focused by a lens 5, 6, 7 on an electrode 8, which may have an aperture similar to that in the diaphragms and with its mutually perpendicular edges parallel to those of the image of the diaphragm, or may be solid with a corresponding boundary. The image is deflected by the two sets of plates 9, 10 or by magnetic means, so that differing electron currents pass through the aperture in the electrode or fall on it in the two forms described. The current may then be amplified by secondary emission and collected by an anode. The variation in the current is proportional to the product of the deflections produced by the two pairs of plates, so that a carrier may be modulated by applying the carrier signal to one pair and the modulation to the other, or an intermediate frequency signal provided in a superheterodyne circuit by applying the incoming signal to one pair, and the local oscillation to the other. Alternatively, if the same signal is applied to both, an output proportional to the square of the signal is obtained. The device may be used for rectification or amplitude limitation, since its output characteristic has a sharp lower bend, and the diaphragm aperture and control electrode may be shaped to give it a sharp upper bend also. By applying a steady potential to one of each of the pairs of plates the undeflected position of the beam may be adjusted, so that by varying a steady potential on one of the plates carrying the modulant the degree of modulation may be altered. For certain purposes this control may be mechanically coupled with one which alters the carrier amplitude, so that a definite relationship between carrier amplitude and degree of modulation may be preserved.

Abstract: 951,847. Coffee percolators. SUNBEAM CORPORATION. March 22, 1962 [June 14, 1961], No. 11028/62. Heading A4D. A coffee percolator has a shallow pump chamber 22 formed by a depression in the base 14 of its liquid container 1 and an electrical heating element 23 is brazed on to the bottom wall 16 of this chamber. The chamber is sealed by a gasket 9 or an upper closure plate 17 having a silent operating one-way inlet valve 19 (Fig. 3, not shown) and upwardly extending percolator tube 18. When a lid 2 to the container 1 is in position its knob 6 presses on a perforated cover plate 7 to a perforated coffee basket 8 fixed to the percolator tube, causing a spring 32 inside a tubular extension 30 to the cover 7 to be pressed down by a flange 31 and exert downward thrust on a rib 33 fixed to the tube 18. The downward thrust on the percolator tube holds the closure plate 17 in position. Automatic electrical control means secured to the container base is enclosed by a watertight cap 3 and operated by an external knob (not shown) to provide a mild or strong brew. The cap 3 is secured by a bolt 39 which screws into a resilient connector 86 fixed to a bracket 81 brazed on to the container base. External terminals 48, removable to allow cap 3 to be removed, form part of an electrical circuit, Fig. 11, in which the main heater 23 is of high voltage, e.g. 1000 watts and is connected in parallel with a keep-warm heater 15 of low wattage, e.g. 40 watts until the coffee is ready when heat conducted from the coffee through a lug 102 brazed on to the base 14 of the container causes a bimetallic actuating strip to separate contacts 66, 67 and establish a series connection between the heaters, which virtually cuts out heater 23, heater 15 then taking over to keep the coffee warm. The circuit switch over also causes an indicator lamp visible through a translucent insert in cap 3 to be extinguished and takes place if the container 1 is empty. The heater 15 communicates, through a thermally conductive strap 108 sandwiched between mica boards and an integral arm 116, sufficient heat to the bimetallic strip to keep contacts 66, 67 apart. The exterior control knob connects with an adjusting member 123 which bears against the arm 95 carrying contact 66 with a stronger or weaker pressure, a higher or lower temperature then being required respectively to separate the contacts 66, 67.

Abstract: 527,647. Electromagnetic interrupters; discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. April 12, 1939, No. 11103. Convention date, April 12, 1938. [Class 38 (v)] [Also in Group XL] An interrupter, particularly for starting a discharge lamp, comprises an electromagnet 17, an arm 51 pivoted at 37, and biassed by a spring 49 so that the contact 43 tends to engage the fixed contact 44; the arm carries an iron screw 40 acting as armature and surrounded by a rubber block 42 acting as a bumper to prevent the armature actually touching the pole 18 of the magnet. The energizing circuit of the magnet includes the contacts 43, 44 and is thus broken when the armature is attracted by the magnet pole 18. To prevent the armature vibrating with the alternations of the alternating current, the arm 51 is made sufficiently massive and its frictional resistance to movement may also be adjustably increased, Figs. 2 and 3 (not shown). In a modification, Figs. 4 and 5 (not shown) the arm is mounted on roller bearings, its inertia alone being relied upon. The interrupter is adapted to " start " a gaseous electric discharge lamp 10 and is connected in series with the electrodes 56, 57 when main switch 11 is closed. The electrodes are heated by the current and the continual interruption of the circuit causes a series of voltage impulses, which, when the electrodes are hot enough, starts the discharge. The interrupter contacts 43, 44 are then held permanently open.

Abstract: 710,419. Thermionic valves. M-O VALVE CO., Ltd., and BELL, J. May 12, 1952 [May 11, 1951], No. 11231/51. Class 39(1) A thermionic valve having a filling at least partly of hydrogen and provided with a sealed container 11 containing a substance which evolves hydrogen on heating, as in Specification 663,290, is characterized by the provision of an auxiliary heater 12 for heating the container 11 when it is not sufficiently heated by the anode. In operation at the normal maximum loading the container 11 is heated sufficiently by the anode to release hydrogen and maintain the pressure of the hydrogen filling, the container being permeable to hydrogen at high temperatures; in operation at reduced loading the heating by the anode is insufficient and the auxiliary heater 12 is energized. The voltage applied to the heater 12 may be varied continuously, or in discrete steps, and may be controlled conjointly with the loading of the valve, for example by a ganged switching arrangement. The container 11 may be of nickel, copper, iron or palladium, and it may contain the hydride of zirconium, titanium, tantalum, vanadium, or thorium; it may be disposed on the cathode heat shield instead of on the anode. According to the Provisional Specification it may be filled with hydrogen at a pressure greater than that of the filling. Specifications 663,290 and 663,304 are referred to.
